CHARGE PUMP

摘要

One charge pump includes at least one delay element, a number of inverters, and a flip flop coupled in series, with an output of one inverter coupled in a feedback loop to one of the delay elements. The charge pump monitors a first supply voltage level, and turns off an oscillator of the charge pump when the first supply voltage drops below a certain level. This is accomplished in one embodiment by monitoring a first supply voltage level supplied to a charge pump, and turning off an oscillator of the charge pump when the first supply voltage drops below a certain level.

主权项

1. A method for operating a charge pump, comprising:
monitoring a level of a supply voltage of a charge pump; and turning off an oscillator of the charge pump responsive to the level of the supply voltage dropping below a certain level, wherein turning off the oscillator comprises setting an inverter of the oscillator to a steady state output.
